Abstract
<p indent="0mm">The mission characteristics of Tianwen-1 Mars Probe, and the complicated environment during the entry descent and landing (EDL) and the rover exploration put forward a high demand for ground validation technology. At the research and development stage, in addition to conventional spacecraft tests, many special tests for the mission goals and the Mars environment characteristics are carried out. The adequacy of the ground test ensures the successful implementation of the mission. After the introduction of ground verification requirements, the system-level special test planning, implementation, and test results are thoroughly described. Finally, the ground test methods and test technology of the Tianwen-1 Mars probe are summarized. It has an important reference for future ground verification of deep space landing probes.
